Two cases of intra-articular median nerve entrapment after reduction of elbow dislocations in children are described. The diagnosis of median nerve entrapment is often delayed. A proximal median nerve deficit, limited passive elbow motion, and an associated medial epicondyle avulsion after reduction of a child's posterior elbow dislocation should alert the surgeon to the possibility of nerve entrapment. Optimal management of this problem consists of early surgical exploration and nerve release.

Both moving and static two-point discrimination are valid measurements of functional sensibility in the hand. The present study investigated the interobserver variability of these measurements when two observers used the same testing instrument and the same definition of the testing procedure's end point. ⋯ Measurements for both moving and static two-point discrimination were analyzed statistically by linear regression and correlation co-efficient techniques. The measurements for two-point discrimination obtained with the protocol employed in this study were found to have an interobserver reliability at the p less than 0.00001 level.
